1 DULAS ISLAND CLOSE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Caerphilly local authority area over time, sourced from the HPI. The two 1 DULAS ISLAND CLOSE sales from April 2015 and October 2020 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the April 2015 sale was for 56% above the HPI. So the extrapolation line tracks at 56% above the HPI over time, until the October 2020 sale, where it falls to 50% above the HPI. The line then continues to track at 50% above the HPI.

What might 1 DULAS ISLAND CLOSE be worth now?
